term.
The vertex is given as . That means,
and
So, the vertex form will be:
Given that, when the x-value is 4, the y-value is 3. So, plugging these values into the above equation, we will get.....
Thus, the coefficient of the squared expression in the parabolas equation will be 5.
Answer:
option B and C
Step-by-step explanation:
Lets check each function
Lets simplify
factor the numerator
Cancel out x+5 so we are left with x-5
When x=-5 then f(x) = x-5= -5-5 = -10
To make the function continuous at x=-5 the value of f(x) should be -10
So option B is correct
Now we check with option C and D
Lets simplify
factor the numerator
Cancel out x+5 , so we are left with x+5
When x=-5 then f(x) = x+5= -5+5 = 0
To make the function continuous at x=-5 the value of f(x) should be 0
So option C is correct
